Question

A box is in the form of a cuboid whose external measures are 50cm×40cm×25cm. The base, the side faces and back face are to be painted black. Find the area to be painted.​

Answer 1

Answer

The dimensions of cuboid are 50×40×25

The Lateral surface area of cuboid is given by 2h(l+b)

Here l=50;b=40;h=25

Lateral surface area is 2×25(50+40)=50(90)=4500

And the base area is given by lb=(40)(50)=2000

So The total area is given by 4500+2000=6500
